Filterbuy 13x21.5x1 Air Filter MERV 8 Dust Defense (4-Pack), Pleated HVAC AC Furnace Air Filters Replacement (Actual Size: 12.88 x 21.50 x 0.75 Inches)

Clean filters are a must

just what I needed

Got a box of 4, one was defective. Reached out to seller and they will be sending a replacement. They have a good mesh on the filter material and good cardboard support. Haven't trialed one yet so we will see how filter material performs. Would like to see more pleats for better airflow and greater longevity. Its not a high Merv filter so it will work in my blower.

I purchased the Filterbuy 12x24x1 MERV 8 air filters and have been very happy with them so far. They fit perfectly in my HVAC system without any gaps or issues during installation. After replacing my old filters, I noticed the air in my home feels cleaner and there seems to be less dust settling around the house. They do a good job of capturing everyday particles and allergens while still allowing good airflow. Overall, this is a reliable and cost-effective 4-pack of filters. Solid quality, easy to install, and a noticeable improvement in air freshness. I’ll definitely be ordering again.

5 étoiles parce qu’il est facile à entrer dans l’espace… du fait qu’il est un tout petit peu plus petit que 20 pouces (un demi pouce de moins) Habituellement il faut presque se battre avec les filtres pour les faire entrer. Aussi cette fois j’ai pris des filtres M8 au lieu des M3 ou M5. Un peu de recherche explique bien ce que chacun filtre le plus (climatiseur)
